Question 3

1 / -0

Use the following information to answer the next question.

Burning of fossil fuel produces CO₂ gas in the atmosphere. It is a greenhouse gas that traps the solar radiations in the atmosphere and results in the greenhouse effect. Some of the consequences of the greenhouse effect are- sudden rainfall, an increase in the average temperature, melting of glaciers leading to a rise in the ocean levels etc.

Which phenomenon is described in the information provided?

Acid rain

Water pollution

Global warming

Ozone layer depletion

Question 4

1 / -0

Use the following information to answer the next question.

Four events that result in the greenhouse effect are resulted below:

I. Earth reflects a part of sunlight

II. Trapped radiation heats up the atmosphere

III. The Earth’s atmosphere traps the reflected sunlight.

IV. Sunlight falls on the surface of the Earth.

Which arrow diagram correctly represents the sequence of events that result in the greenhouse effect?

I → II → III → IV

I → IV → III → II

IV → III → II → I

IV → I → III → II
